Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, in particular to a cutting device for producing particleboards. Background Art

[0002] The field of cutting device technology encompasses various devices and processes used to separate materials. The core of this technology involves separating materials through mechanical action or energy application, including sawing, shearing, laser cutting, and other methods. A systematic introduction covers cutting principles such as tool motion, material retention mechanisms, and cutting force control. Common types include circular saws, band saws, and water jet cutting equipment, with applications extending to industries such as wood processing, metal manufacturing, and building materials production, ensuring precision and efficiency in the material separation process.

[0003] The patent application title "Particleboard Production Cutting Device" refers to a device specifically designed for use in the particleboard manufacturing process. The patent addresses the precise slicing and continuous batch cutting of particleboard. The patent utilizes a rotating saw blade, a guide rail positioning system, and a conveyor belt mechanism to achieve the material separation task, based on a mechanical structural design.

[0004] The existing technology only cuts particleboard through rotating saw blades, guide rail positioning and conveyor belt transportation, and lacks targeted fixation and support near the cutting line.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, a cutting device for particleboard production, see Figure 1 and Figure 2 , including a base 1, the upper end of the base 1 is fixedly connected to a shell 2, an intermittent blanking structure 3 is fixedly installed on one side of the inner surface of the shell 2, and a blanking roller 6 is fixedly installed on the side of the inner surface of the shell 2 away from the intermittent blanking structure 3. An explosion-proof edge auxiliary structure 4 is provided in the middle of the upper end of the base 1, and a cutting structure 5 is provided at the top of the inner surface of the shell 2. The explosion-proof edge auxiliary structure 4 includes a guide component 41 installed on the upper end of the base 1, and a fixed support component 43 is provided on the inner surface of the guide component 41. The outer surface of the fixed support component 43 is provided with a dust collecting box 42 that is slidably connected to the bottom wall of the inner surface of the shell 2.

[0034] During the operation of this embodiment, the particleboard fed by the intermittent feeding structure 3 is fixed and fed into the action range of the cutting structure 5 by the cooperation of the guide component 41 and the fixed support component 43 arranged at the upper end of the base 1. The particleboard is fixed by the action of the fixed support component 43, and at the same time, the cutting line is limited and supported by the cutting structure 5. By providing auxiliary force near the cutting line, the particleboard remains stable during the cutting process, the occurrence of edge chipping is reduced, and the cutting quality is improved.

[0035] It should be noted that the intermittent unloading structure 3 is a conventional intermittent unloading device for plates, which is controlled by a control terminal (not shown in the figure). When the explosion-proof edge auxiliary structure 4 is located below the intermittent unloading structure 3, the intermittent unloading structure 3 conveys a particle board downward. This structure has a variety of implementation forms, all of which are conventional technical means in the prior art. The specific implementation method and specific structure will not be described in detail in the present invention.

[0036] Similarly, the unloading roller 6 can send out the cut plate on the upper part through friction after the explosion-proof edge auxiliary structure 4 reaches the other side, thereby realizing the unloading function, and its implementation method is also a conventional technical means in the prior art.

[0037] Example 2: Based on Example 1, this example further realizes stable cutting of the particleboard through the cooperation of the drive box 51, the telescopic drive rod 52 and the conical block 56 in the cutting structure 5; the drive box 51 drives the saw blade 53 to rotate, and the telescopic drive rod 52 drives the saw blade 53 to move up and down to adapt to different cutting depths, while driving the fixed plate 55 to move downward, and the conical block 56 first contacts the particleboard through the friction roller 57, and the compression spring 59 is forced to expand to make the saw blade 53 continue to move downward to the predetermined depth, and the friction roller 57 squeezes both sides of the cutting line to avoid edge collapse caused by uneven force at each layer during cutting.

[0038] For further information, see Figure 3 The cutting structure 5 includes a drive box 51 fixedly connected to the top wall of the inner surface of the shell 2, and a telescopic drive rod 52 is slidably connected to the inner surface of the drive box 51. The lower end of the telescopic drive rod 52 passes through the bottom wall of the inner surface and extends to the lower end of the drive box 51 and is rotatably connected to a saw blade 53 driven by a belt. The front and rear ends of the telescopic drive rod 52 are symmetrically fixedly connected to fixed plates 55. Top plates 54 are provided on the upper parts of the two fixed plates 55. The lower ends of the two top plates 54 are fixedly connected to a number of compression springs 59 fixedly connected to the adjacent fixed plates 55 in an array. The lower ends of the two top plates 54 are fixedly connected to limit rods 58 that pass through the upper ends of the fixed plates 55 and extend to the lower ends of the fixed plates 55 in an array. The lower ends of the limit rods 58 on the same side are commonly fixedly connected to a conical block 56. The lower ends of the two conical blocks 56 are rotatably connected to a number of friction rollers 57 distributed in an array.

[0039] It should be noted that the drive box 51 is equipped with a drive motor and a control device for driving the telescopic drive rod 52 to extend and retract. The motor drives the saw blade 53 to rotate, and the extension and retraction of the telescopic drive rod 52 drive the saw blade 53 to move up and down in the housing 2 to meet the cutting requirements of different depths. The installation and driving methods of the drive box 51, telescopic drive rod 52 and saw blade 53 are mature technical means in the existing technology. Their specific structure and operating principle will not be displayed or elaborated in the present invention.

[0040] The saw blade 53 is driven downward by the action of the drive box 51 and the telescopic drive rod 52, and the fixed plate 55 is driven downward by the action of the telescopic drive rod 52 on the fixed plate 55. Under the action of the compression spring 59 and the top plate 54, the bottom conical block 56 is initially lower than the lower edge of the saw blade 53. When the friction roller 57 contacts the particleboard, the continued displacement of the top plate 54 will be limited by the conical block 56 and the limit rod 58. At this time, the compression spring 59 is forced to expand, and the saw blade 53 continues to move downward without restriction until the lower edge of the saw blade 53 reaches the predetermined cutting depth. At this time, the friction roller 57 is pressed on the upper edge of the particleboard, and by squeezing both sides of the cutting line, the edge collapse caused by uneven force on each layer of the cutting surface during the cutting process is avoided.

[0041] Embodiment 3: Based on embodiment 2, this embodiment further realizes stable clamping of the particle board through the cooperation of the guide component 41 and the fixed support component 43; the limiting guide rail 411 and the U-shaped slide 415 guide the Y-shaped support block 434 to slide horizontally, and the sliding shaft 4342 rises after entering the U-shaped slide 415, pushing the movable rod 4345 to send the hydraulic oil of the slide 2 4346 into the clamping component 432 through the connecting pipe 2 4348, and the L-shaped rod 4321 in the hydraulic chamber 4323 drives the spring block 4322 to fit the side wall of the particle board, and cooperates with the top conical block 56 and the friction roller 57 to reduce the cutting offset.

[0042] Furthermore, the present invention realizes the support of the particleboard cutting line through the cooperation of the guide component 41, the fixed support component 43 and the base plate 431; the clamping drive guide rail 412 guides the movable rod 4343 to rise and fall, and the hydraulic oil of the compression slide 4344 enters the base plate 431 through the connecting pipe 4347, and the hydraulic rod 4332 pushes the trapezoidal block 4333 to make the contact block 4334 rise, providing an upward and cutting line force to the particleboard, and cooperates with the conical block 56 and the friction roller 57 to form a "rigid protective cover" to offset the cutting stress, avoid edge collapse, and improve the quality of the cutting surface.

[0043] For further information, see Figure 4 The guide assembly 41 includes two limiting guide rails 411 that are symmetrically distributed front and back and fixedly installed on the upper end of the pedestal 1. The part of the upper end of the pedestal 1 located between the two limiting guide rails 411 is fixedly connected with a clamping drive guide rail 412. The limiting guide rails 411 and the clamping drive guide rail 412 are both slidably connected to the fixed support assembly 43, and the upper ends of the two limiting guide rails 411 are fixedly connected with a supporting drive guide rail 413.

[0044] For further information, see Figure 5The two limiting guide rails 411 are each provided with a straight slide groove 414 at one end close to each other, and the two supporting drive guide rails 413 are each provided with a U-shaped slide groove 415 at one end close to each other. The left and right sides of the U-shaped slide groove 415 pass through the upper end of the limiting guide rail 411 and extend to the inner cavity of the straight slide groove 414. The depth of the U-shaped slide groove 415 within the range of the straight slide groove 414 is less than the depth of the straight slide groove 414. The middle part of the clamping drive guide rail 412 is raised and its raised width is less than the width of the horizontal part of the U-shaped slide groove 415.

[0045] The limiting guide rail 411 and the straight slide groove 414 are mainly used to limit the movement direction of the fixed support component 43 to left and right movement, while the clamping drive guide rail 412 mainly cooperates with the Y-shaped support block 434 to drive the supporting component 433, so that it provides support for the lower side of the particleboard cutting line, and the supporting drive guide rail 413 and the U-shaped slide groove 415 cooperate with the Y-shaped support block 434 to drive the clamping component 432, the quota and conical block 56, and the friction roller 57 clamp and fix the particleboard to avoid offset during the cutting process.

[0046] For further information, see Figure 5 and Figure 6 The fixed support assembly 43 includes a Y-shaped support block 434 that slides left and right on the upper end of the base 1 through an electric screw drive. The Y-shaped support block 434 is located between the two limiting guide rails 411 and is slidably connected to the upper end of the bottom clamping drive guide rail 412. The upper end of the Y-shaped support block 434 is fixedly connected to the bottom plate 431 symmetrically front and back. The two bottom plates 431 are symmetrically provided with clamping parts 432 on the side away from each other, and the two bottom plates 431 are provided with supporting parts 433 on the end close to each other.

[0047] The clamping component 432 is used to clamp the edge of the particle board. During the feeding process, the particle board is clamped and fixed by two groups of clamping components 432 on both sides, and the supporting component 433 at the bottom is used to pre-support and limit the area near the cutting line of the particle board. Furthermore, the Y-shaped support block 434 set at the lower end of the base plate 431 cooperates with the guide component 41 to realize the segmented driving of the clamping component 432 and the supporting component 433, so that they can realize different actions at different positions, thereby clamping and supporting the particle board.

[0048] For further information, see Figure 7 and Figure 8The front and rear ends of the Y-shaped support block 434 are symmetrically fixedly connected with sliders 4341 that are slidably connected to the inner surface of the adjacent straight slide groove 414. The width of the slider 4341 is smaller than the width of the U-shaped slide groove 415. The inner surface of the Y-shaped support block 434 is symmetrically provided with a slide groove 4344. The inner surfaces of the two slide grooves 4344 are slidably connected with a movable rod 4343 through a spring. The lower ends of the two movable rods 4343 are slidably connected to the upper end of the clamping drive guide rail 412 through rollers. The top wall of the inner surface of the movable rod 4343 is provided with a connecting pipe 4347 that is connected to the supporting component 433.

[0049] The slider 4341 slides horizontally in the straight slide groove 414 to limit the movement trajectory of the Y-shaped support block 434, so that it moves along a predetermined cutting trajectory and cooperates with the saw blade 53 to cut the particleboard in a straight line. At the same time, since the width of the slider 4341 is smaller than the width of the U-shaped slide groove 415, the slider 4341 will not be guided by the U-shaped slide groove 415, but will continue to slide in the linear track of the straight slide groove 414, thereby limiting the movement trajectory of the Y-shaped support block 434 to a horizontal straight line.

[0050] Furthermore, during the horizontal movement of the Y-shaped support block 434, the movable rod 4343 slides on the clamping drive guide rail 412 and moves synchronously along the path of the clamping drive guide rail 412. When the movable rod 4343 moves from the horizontal part of the clamping drive guide rail 412 to the raised part, the movable rod 4343 retracts into the slide groove 4344. The hydraulic oil in the slide groove 4344 is pressed by the movable rod 4343 and enters the adjacent supporting component 433 through the connecting pipe 4347, thereby driving the supporting component 433 to move, thereby realizing the driving of the supporting component 433 and then realizing the support of the particle board.

[0051] For further information, see Figure 7 and Figure 8 The inner surface of the Y-shaped support block 434 is slidably connected to a sliding shaft 4342 that is adapted to the width of the U-shaped slide grooves 415 on both sides. The inner surface of the Y-shaped support block 434 is provided with a second slide groove 4346. The inner surface of the second slide groove 4346 is slidably connected to a movable rod 4345 through a spring. The lower end of the movable rod 4345 is tightly attached to the central axis of the sliding shaft 4342. The upper end of the second slide groove 4346 is symmetrically provided with a second connecting pipe 4348 that is connected to the adjacent clamping component 432.

[0052] Under the action of the Y-shaped support block 434, the sliding shaft 4342 will slide in the straight slide groove 414. When the sliding shaft 4342 moves to the position where the straight slide groove 414 and the U-shaped slide groove 415 meet, since the path depth of the U-shaped slide groove 415 is less than the path depth of the straight slide groove 414, and the depth of the sliding shaft 4342 matches that of the U-shaped slide groove 415, the sliding shaft 4342 will be guided by the U-shaped slide groove 415 and enter the track of the U-shaped slide groove 415, and will not move along the horizontal track of the straight slide groove 414.

[0053] During this process, the U-shaped slide grooves 415 on both sides gradually guide the sliding shaft 4342 to rise in the inner cavity of the Y-shaped support block 434, thereby pushing the movable rod 4345 to rise, thereby sending the hydraulic oil in the second slide groove 4346 into the clamping parts 432 on both sides through the second connecting pipe 4348, driving the clamping parts 432 to clamp the particle board.

[0054] For further information, see Figure 9 The clamping part 432 includes a hydraulic chamber 4323 opened on the side of the bottom plate 431 away from the supporting part 433. The inner surface of the hydraulic chamber 4323 is slidably connected to the L-shaped rod 4321 through a spring. The vertical part of the L-shaped rod 4321 is slidably connected to the side close to the bottom plate 431 with a spring block 4322. The inner surface of the hydraulic chamber 4323 is connected to the connecting pipe 2 4348 on the side away from the supporting part 433.

[0055] Hydraulic oil is injected into the hydraulic chamber 4323 through the connecting pipe 4348, thereby pushing the L-shaped rod 4321 toward the direction of the bottom plate 431. At this time, the spring block 4322 is in contact with the side wall of the particle board, and the side wall of the particle board is clamped and fixed under the action of the spring block 4322 and the hydraulic oil. During the cutting process, the conical block 56 and the friction roller 57 set on the top of the particle board are used to further clamp and fix it, thereby reducing the deviation of the particle board during the cutting process.

[0056] For further information, see Figure 10 The bottom plate 431 includes a plurality of slide grooves 4331 distributed in an array and opened on one side of the bottom plate 431 near the Y-shaped support block 434. The bottom walls of the inner surfaces of the plurality of slide grooves 4331 are slidably connected to the trapezoidal blocks 4333. The inner surfaces of the plurality of slide grooves 4331 are fixedly connected to the hydraulic rods 4332 connected to the connecting pipe 1 4347. The piston rods at the output ends of the plurality of hydraulic rods 4332 are fixedly connected to the adjacent trapezoidal blocks 4333. The upper ends of the plurality of trapezoidal blocks 4333 are fixedly connected to the push rods 4335 through relay springs. The plurality of push rods 4335 penetrate the inner surface of the slide groove 4331 and extend to the outer surface of the slide groove 4331 and are slidably connected to the contact block 4334 together. The lower end of the contact block 4334 is fitted with the inclined surface of the trapezoidal block 4333.

[0057] Hydraulic oil is transported to the third slide 4331 through the connecting pipe 1 4347, thereby extending the piston rod of the hydraulic rod 4332. The hydraulic rod 4332 acts on the third slide 4331 to drive the push rod 4335 to extend outward, thereby pushing the first slide 4344 to both sides of the cutting line. Furthermore, after the push rod 4335 and the contact block 4334 are in place, the contact block 4334 is pushed upward by the cooperation of the continuously sliding trapezoidal block 4333 and the contact block 4334, thereby providing a supporting force for the particle board. At the same time, under the action of the push rod 4335, a force perpendicular to the cutting seam is provided, and the plate near the cutting line of the particle board is clamped in cooperation with the action of the tapered block 56 and the friction roller 57 to maintain its stability during the cutting process.

[0058] The force intermittently applied to the lower end of the particleboard by the push rod 4335 and the trapezoidal block 4333 through the contact block 4334 provides an upward force and a force in the direction of the cutting line, respectively. The dynamic force field actively guides the generation, transmission and release of stress. In conjunction with the downward pressure generated by the tapered block 56 and the friction roller 57 at its upper end, a "rigid protective shield" is formed by mechanical force at the moment of cutting, which strictly limits the stress within the cutting line, prevents the surface material from cracking due to stress explosion, and further offsets the radial tearing force and axial shear force generated by cutting. At the same time, it "locks" the surface stress in advance to avoid the edge collapse of the particleboard due to stress release.

[0059] Furthermore, by clamping the particleboard near the cutting line, the tearing force of the tool is offset, the surface layer and the core layer are prevented from separating, the edge collapse phenomenon is avoided, the quality of the cutting surface is improved, and the defective rate is reduced.
